    This study investigated acute lymphoblastic leukemia (ALL) in patients with a specific glucose-6-phosphate dehydrogenase (G6PD) variant. The 2-deoxyglucose-6-phosphate (2dG6P) method confirmed a monoclonal origin for the leukemia, indicating it arose from a single progenitor cell.

    Area of Science:

    • Hematology
    • Oncology
    • Biochemistry

    Background:

    • Acute lymphoblastic leukemia (ALL) is a heterogeneous hematologic malignancy.
    • Glucose-6-phosphate dehydrogenase (G6PD) deficiency, particularly the Mediterranean variant, can influence drug metabolism and treatment outcomes.
    • Understanding the cellular origin of leukemia is crucial for targeted therapies.

    Observation:

    • Three patients with ALL and heterozygous for the Mediterranean G6PD variant were studied.
    • The 2-deoxyglucose-6-phosphate (2dG6P) method was employed to trace the cellular lineage of the leukemic cells.

    Findings:

    • The study established a monoclonal origin for the lymphoblasts in all investigated patients.
    • The leukemic process was confined to the lymphoblasts, with other hematopoietic cell lines remaining uninvolved.

    Implications:

    • This finding supports the hypothesis that ALL arises from a single transformed progenitor cell.
    • The G6PD variant did not appear to influence the monoclonal nature of the leukemic origin in these cases.
    • Further research into G6PD variants and their impact on leukemia development and treatment is warranted.
